Whoever it was seems to have been perusing an inventory, a listing of arrivals in the past three months. The binder supplies a small photograph, the description, name, artist, arrival date and a reference to the insurance ID, though some are missing an insurance entry. On the table beside it is a log file. Looks like it was being cross referenced.
The room seems to flicker slightly. The details shift ever so slightly, some of the words becoming a vague squiggle. Under pressure, the illusionist seems to be getting careless with details. The sound of footsteps echo down the corridor outside.
Kaleidoscope senses something just slightly off. There's a stack of binders that weren't there before, just out of her line of sight and artfully lost in the clutter of binders and files. It would have gone entirely without notice if she wasn't expecting a trick like this. The small heap must be concealing something.
